Racing Metro utility back Frans Steyn is one of five players recalled to the South Africa training squad ahead of the home leg of this year's Tri-Nations.

The 23-year-old Rugby World Cup winner joins Cheetahs flankers Juan Smith and Heinrich Brüssow, Sharks wing JP Pietersen and Sharks hooker Bismarck du Plessis in a training squad of 29 players that will attend a four-day camp in Johannesburg next week in preparation for the side's last three Tri-Nations clashes against New Zealand in Johannesburg (August 21) and Australia in Pretoria and Bloemfontein (August 28 and September 4).

However, Steyn, who last played against Wales in June, was injured in a pre-season game on Friday and will undergo a scan in Paris on Tuesday to determine the extent of the injury. Du Plessis returned to action with Natal Sharks this past weekend while Smith has also battled back from injury and has featured for the Cheetahs in this year's Currie Cup. Brussow is included despite having been out of action since February after undergoing surgery for a knee injury.

The group also includes the bulk of the squad that suffered back-to-back defeats to the All Blacks and another against the Wallabies last month with only lock Andries Bekker and scrum-half Ruan Pienaar unavailable due to injury. Centre Jaque Fourie is serving a suspension and cannot be considered for selection for the Johannesburg Test on 21 August.

The final squad of 24 for the three Tests will be confirmed on Friday, August 13 with the match 22 for the clash against the All Blacks at the National Stadium (formerly Soccer City) will be announced on Tuesday, August 17.
